how do they size them? im 14 right now and if i put my hat on and size it, the size goes from 23(inches) and a quarter to 24. This means the circumference of my head in cm is 60.96. A Xlarge is 59 to 60 and a XXl is 61 to 62. I also wear goggles under my helmet but i don't think it gets in the way. So do i go for a XXL? or what
